Supercritical carbon dioxide extraction (SC-CO2) was performed to recover the lipid fraction of cake by-product from Brazil nut beverage (BNM) production. Extraction kinetics and effect pressure temperature on yield, oil recovery, fatty acid (FA) profile minor compounds were evaluated. The modeling kinetic assays indicated that most is readily accessible velocity dominated by solubility. High y...

Fatty acid (FA) compositions in tissues are related to metabolic disorders, and consequently the appropriate management of underlying FA compositions in tissues is considered to be important. However, the relationship among the serum lipid profiles, the FA composition of the red blood cell (RBC) membranes and genetic variations in the fatty acid desaturase (FADS) genes in Japanese men is unclea...

The fatty acid (FA) content of fish is generally said to reflect fatty acid composition of the diet. In fact, incorporation of FA into tissues is modulated by various metabolic factors, and final composition will depend upon the initial FA content, cumulative intake of dietary fatty acids, growth rate and duration. Analysis of time course of changes in FA composition should be easier with anima...

A method developed at AgResearch to increase leaf fatty acids (FA) and plant growth called ‘High metabolizable energy’ (‘HME’) could elevate the nutritional quality productivity of perennial ryegrass-based pastures. The industry strategy has been perform HME ryegrass field trials offshore test whether herbage FA, gross energy (GE) yield enhancing traits observed in containment translate into sw...

BACKGROUND Phosphatidic acid (PA) is a key regulated intermediate and precursor for de novo biosynthesis of all glycerophospholipids. PA can be synthesized through the acylation of lysophosphatidic acid (LPA) by 1-acyl-3-phosphate acyltransferase (also called lysophosphatidic acid acyltransferase, LPAAT). Recent findings have substantiated the essential roles of acyltransferases in various biol...

Increased plasma NEFA concentrations and compromised immune responses are associated with increased disease susceptibility during farrowing and lactation. Increased plasma NEFA concentrations cause changes in the fatty acid (FA) content of plasma lipid fractions and peripheral blood mononuclear cells (PBMC) that could modify inflammatory responses. The goals of this study were to describe chang...

Weaned rabbits were fed diets contaminated with 2 mg/kg diet T-2 toxin alone, or 10 mg/kg diet fumonisin B1 (FB1) alone, and both toxins in combination (2 + 10 mg/kg, respectively) compared to a toxin-free control diet. Samplings were performed after 4 weeks (blood and liver). Bodyweight of T-2-fed group was lower after 4 weeks; the liver weight was increased dramatically (threefold of control)...

Folate is a water-soluble vitamin that is critical for nucleotide synthesis and can modulate methylation of DNA by altering one-carbon metabolism. Previous studies have shown that folate status during pregnancy is associated with various congenital defects including the risk of aberrant neural tube closure. Maternal exposure to a methyl supplemented diet also can alter DNA methylation and gene ...

We supplemented diets with α-tocopheryl acetate (100 mg/kg) and replaced beef tallow (BT) in feeds with increasing doses of n-6- or n-3-rich vegetable fat sources (linseed and sunflower oil), and studied the effects on the fatty acid (FA) composition, the α-tocopherol (αT) content and the oxidative stability of rabbit plasma and liver. These effects were compared with those observed in a previo...
